TITLE:
INTRODUCTION
ADVANCED COMPUTER CONCEPTS FOR THE (NOT SO) COMMON CHEF
While talking to a very intelligent but non-engineer colleague, I found myself needing to explain the threading and other components of the Intel® Xeon Phi™ ⅹ100 and ⅹ200 architectures. The first topic that came up ...

Hello again.
Now where did I leave off? Let us see, I was talking about IDF14 (Intel Developer’s Forum 2014). Ah, now I recall. I want to talk about the IoT (Internet of Things) sessions, particularly the labs.
First off, the demos were fun. It is one thing to puzzle about what an ...

I attended IDF14 (Intel Developers Forum 2014). I was invited because I achieved something called “Black Belt” status this year, meaning that someone believes that I have a certain modicum of influence within the scale developer community. Personally, achieving this status evokes equal mixtu...

I don’t know if any of you have noticed but Intel® has a tendency to emphasize its own homegrown tools. This isn’t bad as Intel has some of the best. Still, if someone has a favorite hammer, there’s a tendency to use that hammer for just about everything.
What I want to do here is to talk about ...

How about the future? Have we reached the pinnacle of power management?
Hardware and software are still evolving to be even more energy efficient. An example is the “tickless” OS. In the old days, OSs had to periodically wake up the processor (i.e., perform an interrupt) around a hundred times a...

Power management policy has evolved over the years. The earliest policies consisted of little more than some critical temperature sensors and an interrupt routine that attempted (often unsuccessfully) to cleanly shut down the system before something really bad happened. Today’s sophisticated powe...

We have all had our little discoveries and triumphs in identifying new and innovative approaches that increased the performance of our applications. Occasionally we find something more, something that could also help others, an innovative gem. You now have an opportunity to broadcast your successes more widely to the benefit of our community.
You are invited to submit a proposal to a contribution-based book, working title, “High Performance Parallelism Gems – Successful Approaches for Multicore and Many-core Programming” that will focus on practical techniques for Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor parallel computing. Submissions are due by May 29, 2014.

Unlike a lot of previous recent blogs, this series is about power management in general. At the very end of the series, I’ll write specifically about the Intel® Xeon Phi™ coprocessor.
I have talked incessantly over the years about power states (e.g. P-states and C-states), and how the processor ...

At SC13 (Super Computing 2013)*, someone commented that Intel seems to have some super-secret set of tricks in its pocket, allowing us to optimize “far beyond those of mortal man”+. We don’t really have any super-secret tricks. Even if we did, we wouldn’t use them. We want mortal man (you) to be ...

Hi all,
I just wanted to let whoever is listening that I just published updates to the Resource Guide for Intel® Xeon Phi™ Coprocessor Developers and Resource Guide for Intel® Xeon Phi™ Coprocessor Administrators documents.
